I also saw that AVO says that the value of 99.5uH should be adjusted to exactly that value with the trimmer.
That's good. Your measured transformer looks to match that in the second document, and we have a solid statement of the target inductance.

Could that earlier document be fore the output transformer on the oscillator board?
